Note:
handset can pick up the tones from the fax machine and change itself into the fax
mode. To prevent this, set the FAX field to off, and put the FAX machines in an
ARS partition that uses only circuit switched trunks, even for IGW FAX calls.

Usage
Turn off special fax handling when using this codec set. In this
case, the fax is treated like an ordinary voice call.
With a codec set that uses G.711, this setting is required to send
faxes to non-Avaya systems that do not support T.38 fax.
For users in regions using this codec, use Avaya relay mode for
fax transmissions over IP network facilities. This is the default for
new installations and upgrades to Communication Manager
R2.1.
For users in regions using this codec, use pass-through mode
for fax transmissions over IP network facilities. This mode uses
G.711-like encoding.
For users in regions using this codec, use T.38 standard
signaling for fax transmissions over IP network facilities.
Usage
Enter the bandwidth limit for Direct-IP Multimedia
transmissions on this codec set. Default is 256.
Usage
Enter the unit of measure corrsesponding to the value
entered for bandwidth limitation. Defalult is kbits.
